Nitrogen and Phosphorus Fertilization on a Long-Term No-Tillage Corn, Soybean, and Wheat Rotation

IPNI-2015-USA-VA25

Continuous no-till corn–wheat-soybean crop rotations (three crops in two years) are common in the mid-Atlantic USA. Poultry litter (PL) can serve as a fertilizer source, however, N-based application rates of PL result in over-application of P relative to crop requirements. Addition of aluminum sulfate (alum) has shown to reduce water-soluble P in PL. Read more
